question about boost guage and map line

I'm installing a boost gauge on my truck. I have a "vacuum/boost" gauge that seems to be on a continuum - if there's vacuum, it goes "0 to-20" and if there's boost it goes to "0 to +30". It's a cheapie I picked up awhile back from Pep Boys, I think. It's only got one input line. Is there any problem using this for a boost gauge? I'm trying to verify if I've got boost and don't want to spend the cash on good gauges til I get the truck running right.

My other question is re: the map line. From the great writeup at Stealth Automotive (http://stealth-automotive.com/docume...%20Install.pdf) I figured out the map line is a line I had to cut the tip off and shorten it, because it was leaking. Now it's a bit short. I'm thinking I should replace this line. What type of hose do I need to replace it with? Is there special vacuum hose, or just heater hose of the same diameter?

Thanks for the help.

Diesels dont create vacuum. Vacuum is measured at the throttle body, which diesels dont have. Any vacuum line will work to replace your map line.

You shouldn't need to install a guage to verify that you have boost. That should be noticable while driving. Without boost the truck is a dog and difficult to drive. Having a boost tube blow off will show you quickly what these trucks are like without the turbo.

I tried to install my cheap boost/vacuum gauge from PepBoys and ran into problems - the hard plastic hosing that came with the gauge is only about 2.5 feet long - nowhere near long enough to go from the map lie to the gauge in the truck. Also, the plastic hosing is less then 1/8 inch - I can't find a "T" that will fit the map line (1/4" or so inner diameter) and also fit the 1/8" hard plastic vacuum line.

Do I just have to buck up and buy a better quality gauge? Do the better gauges come with long enough line to go from the map line, through the firewall and into the cab?

Thanks for the help.
